Whilst the presence of a body fluid may in itself be of relevance, the evaluation of the findings will often need to consider the distribution of the staining. For example, Blood Pattern Analysis can help establish whether an object has been used as a weapon or simply come into contact with wet blood or whether an individual was the assailant or a bystander. It can also be used for scene interpretation to establish the events that have taken place. The distribution of other body fluids such as semen and urine can assist in the evaluation of alternative prosecution and defence scenarios, particularly in sexual offences cases.
In most cases, it will be important to establish who the body fluid has come from via DNA profiling. A full interpretation of the findings will need to take into account not only the DNA results but also the body fluid tests that have taken place together with the distribution of that staining.
